The belt fork q is provided with two pro'ections g, g for purposes to be describe The pendant projection g is arranged to oscil late between two lugs n formed on the bracket 3. In the lugs u are. respectively 1 mounted the set screws o,provided with lock nuts, which act 'as stops for adjusting and regulating the movement of the projection (1 and consequently of the belt itself. The second lugg projects at or about a right angle from the lower portion of one of the sides of the belt fork g, and the lug has attached thereto a spring w the upper end of the latter being connected to a pin as fixed to the standard a. On one side of the lug (f is formed a projection yin which is a hole through which the connecting rod z,having an' enlarged tapering or other head-passes. The lower end of the rode is attached to treadle 1 pivoted at 2 to the ..framework 0. m is a protection cover for the pulleys m, n and belt not shown.

The work support (I is so shaped as to permit of a V-shaped recess 3 being formed therein for the passage of the seam to and 30, under the pressing iron h. In some cases, when required,-but ,not necessarily so.-a

protuberance 4 is formed at the inner end of the V-shaped recess and when such protuberance or swelling 4 is employed it performs uthe function of a seam opener. The V- shaped recess 3,shown in plan at Fig. 12,-- is also inclined from its inner outer portion of the work support d, as shown at Fig. 11. During the passage of the seam through the said recess to and under the pressing iron when the protuberance or swelling 4 is dispensed with, then the operator. in some classes of goods. may have to assist in opening the seam with his or her finger, but in other cases the seam can be opened by passing through the V-shaped recess only. This permits of the dispensing with any special provision for seam opening bein made on the feeding device on its outawar movement.

In machines constructed according to this invention the work support is raised. lowcred. and retained in its working position by the following means The lower end of the rod is bifurcated and at 5 is jointed the end or tongue 6 of the socket 7. In the socket T is formed a central hole having an internal screw thread. The rod or spindle 8 has formed at its upper end a screw thread adapted to engage with the internal screw thread of the socket 7. The rod 8 is arranged to pass through the openings or slits 9 and 10 formed in the flanges or projections 11 and 12 respectively of the framework 0 and the arm a. The

;wheel 13 is shown recessed at end to the toggle lower end of the rod or made plain or has a screw thereon, as at Fig. 19.

In the arrangement shown at Figs. 1 and &

spindle 8 is either thread formed the rod or spindle 8 is providedwith a plain "end and to it is fixed by a pin ,venientmeans a wheel 13 at a or other consuitable distance below the flange or projection 11. The 1% and the upper edges of the recessed portion of the wheel hare formed therein a number of notches 15 with which the projection 10 formed on, or fixed to. a hand lever is made to engage when it is required to turn thewheel for adjusting the position of the work support d. i

In some cases instead of using the herein described arrangement an ordinary. hand wheel may be employed for the same purose. 1

The end of the spindle or rod Sis prolonged beyond the boss of the wheel 13 and fits into a socket 18 provided with a bifurcated end 19 by which the rod is connected to the toggle arrangement. In the end of the 1 03 rod or spindle 8, which passes into the cen-. tral hole of socket 18, is formed a groove 20 into which is passed the end of a set screw 21 (see Fig. t). The set screw and groove. are provided for retaining the end of. the rodi fl fi i in position but yet at the same time permit-a ting of it being rotated as required fora-d justing purposes. By means of the adjustments herein do scribed the work support (Z may be adjusted? s to the varying thicknesses of the seam; belllfli operated upon.

On a spindle 22 is mounted either a disc or a curved plate 23 which forms part of the arrangement. The toggle arrangc-i106 ment shown at Figs. 1, 2 and 4 consists of a central lever portion 2a. the boss part of which is mounted upon the spindle 22. 4X pair of curved plates 22% are cast on. or lixcdito, the central portion Zi -as shown in the 110. said figures'and the lower end of the socket 18 is passed betwe n the two urved plates 23 and secured in working position by their pin 19. The him-r end of the socket 18 is curved and a portion of the upper surface of :24: is cut away to permit off its working freely, To the underside of ther central portion 2% is formed or fixed a lug in which the upper end of a coiled spring 26...- is attached. Thr hirrrr mid of the saidueo spring is attached to a lug 27 formed upon the upper surl'nrc of the trcadle-ZH which is pivoted upon a ipindle 29 carried by the framework 1, in the free end of the central poz'iicu 24; is provided a hole through hirh an adjir ting screw 3' is ar ranged i ag and 11: ou cr end. forms a' stop which is arranged to come in contact with a projection or stop ll formed on the web 19 of the framework 1.

the central part The web 32 is LW QSO perforated a t 33 and 34 so as to form a meansof getting to the set screw for adjust-. ing purposes and to the treadle 28 and spindle 29.

Between the outer ends of the curved plates 23 is passed the upper end of a socket 35 which is mounted upon the pin 36. In the socket is formed a central hole. provided with an internal screw thread with ;-which the screw threaded upper end of a connecting rod 37 is engaged. The lower end of the said rod is provided with an enlarged portion that passes into the. recess. 88 of the treadle 28 and-is secured ;in its working position by a pin 39. The

outer end of the treadle is roughened at 40 and also bifurcated for the reception of a roller 41 mounted upon pin 4-2 carried by the armsof the said bifurcations. This ;;roller is provided so as to reduce the friction in the working of the treadle.

The action of the machine is as follows The work table (I is first lowered by treadle 28 acting upon rod 3'7, curved plates 23, socket 18, rods 8 and c to allow the 'work to be inserted between the top of the workplate and the heated iron h. After this has been done the operator removes the foot from the end of the lever 28 thus allowing the workplate d to return to the position shown in the drawings. The machine is then set in motion by the treadle l acting upon the rod 2 and the belt fork q whereby motion is imparted to the driving shaft Z, thus imparting, by means of eccentries 51 and 71, the required intermittent reciproratin motion for actuating the feeder 50 and the double ended lever f and heated iron h. The V-shaped recess in the workplate into which the seam is passed keeps the seam central with the iron it. The springs 75 and 78 having been adjusted by the nuts is and 77 as previously described, the required intermittent pressure is imparted to the iron for pressing purposes and for raising it clear of the seam to be pressed. The feeding of the said seam under the iron take place when the iron is raised. After a portion of the seam has been pressed, and when it has reached the rear of the work plate d, it passes into recess 92 between the two arms of the framework, or, as in the case of a pair of trousers or a sleeve, after passing over the rear end? ed pressing iron connected with the end of said lever above the garment support, a power shaft, an eccentric mounted on said shaft, a rod connected to said eccentric and extending through the bifurcation in the iron supporting lever. means between said lever and eccentric for determining the pressure applied by the iron to a garment on the support, and an adjustable means within the bifurcation of said lever for controlling said pressure means.
